FIRE-EXTINGUISH ER.

SPECIFICATION forming part of Letters Iatent No. 564,010, dated July 14,1896.

Application filed November 21, 1894. $eri'al No. 529,541. (No model.)

To all whom it may concern.-

Be it known that I, DANIEL FARRELL, J r., residing at Omaha, in thecounty of Douglas and State of Nebraska, have invented certain usefulImprovements in Fire-Extinguishers; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention, suchas will enable others skilled in'the art to which it appertains to makeand use the same, reference being had to the accompanying drawings,which form a part of this specification.

This invention has relation to a new and novel improvement infire-extinguishers, the object being to provide a device that shall besimple of construction and readily operated.

In the accompanying drawings, Figure 1 shows a central sectional view ofa fire-extinguisher embodying my invention. Fig. 2 is a centralsectional view of the bottle valve or stopper, while Fig. 3 shows a topview of the retaining-flange as used in my invention.

A represents the extinguisher proper, and preferably comprises acylindrical metallic vessel, which is provided above with a collar 2,which is preferably threaded and adapted to receive the threaded cap 3,provided with an ordinary operating-handle 4, as is shown. If desired,this cap 3 can be made to snugly fit over the collar 2 and be secured bymeans a suitable retaining-pin. Depending from this cap 3 are twoU-shaped wire loops 5, which loops act as a support and retaining devicefor the bottle B, which is of a size suitable to be inserted betweenthese wires, which are of course flexible, and when inserted this bottleB is snugly held within this retaining-cage. At a suitable point above Iprovide an ordinary nozzled hose 0, as shown. Near the upper end Ifurther provide a metallic disk D, which is provided with a centralopening 6, adapted to receive the wire loops 5. Removably held withinthe bottle B is a valve or stopper E, preferably of lead, having aconical extension which terminates below in a flattened cone 7, and isprovided with an inwardly-extending flange 8, having a series of removedportions 9, as shown.

My improved extinguisher relates to that class of fire-extinguishers inwhich two solutions, one preferably being an acid, are held apart, butwhich, when the extinguisher is to be used, are combined to form a gasto force out the extinguishing-liquid.

In my invention the receptacle A is preferably filled up to the flange D.with any suitable solution, the flange D acting in preventing thesolution from splashing upward. The bottle B is provided with an acid ora reagent Which, when brought into combination with the solution A,generates a gas which forces the solution out of the extinguisher. Inthis instance the solution in the bottle containing the acid is providedwith a preferably leaden stopper E, and when to be used the extinguisheris simply reversed, so that the cap portion 3 comes below. This wouldpermit the dropping of the stopper E, the bottle being securely heldwithin the frame 5, and would allow the acid to freely mix with thesolution within the receptacle proper. The space between the bottle Band the flange D is equal to the thickness of the wire 5, and is spacedso that the fluid in receptacle A proper promptly escapes into the lowerchamber when the receptacle is reversed in such quantities only as to bethoroughly mixed with the escaping acid, so that no great andunnecessary compression of gases occurs within the extinguisher. This isVery important in that the extinguisher can so be made lighter, and isconsequently more easily portable.

The stopper E is provided with a conical base, so that it would upsetand not contain any of the acid within the flange 8, which is providedand forms a hood, so that in case the extinguisher is used in cars ormoving bodies the solution cannot splash into the acid-bottle B.

The device is noticeable because of its extreme simplicity; and,

Having thus described my said invention, what I claim asnew, and desireto secure by United States Letters Patent, is-

In a fire-extinguisher the combination with a casing of a removable cap,U-shaped wire loops, depending from said cap, a receptacle removably'held within said loops, a 100 nozzled hose extending from the upper endarranged substantially as and for the purof said casing, a dished diskwithin and near pose set forth. IO the upper end of said casing,provided with In testimony whereof Iaffix mysignatnre in a centralopening adapted to receive and hold presence of two witnesses.

5 said U-shaped loops and a weighted stopper, DANIEL FARRELL, J R.
